Islam Ashry,Yuan Mao,Yousef Al-Fehaid,Abdulmoneim Al-Shawaf,Mansour Al-Bagshi,Salman Al-Brahim,Tien Khee Ng,Boon S. Ooi +7 more
TL;DR: This work uses an optical-fiber-distributed acoustic sensor (DAS) as a paradigm shift technology for the early detection of red palm weevil and shows a detection of feeding sound produced by larvae as young as 12 days, in an infested tree.
Journal ArticleDOI
Normalized differential method for improving the signal-to-noise ratio of a distributed acoustic sensor.
Islam Ashry,Yuan Mao,Mohd Sharizal Alias,Tien Khee Ng,Frode Hveding,Muhammad Arsalan,Boon S. Ooi +6 more
TL;DR: The ability to locate positions along a fiber that are subjected to vibrations of frequencies higher than the theoretical maximum, but without determining these frequencies is demonstrated.
Journal ArticleDOI
A Review of Distributed Fiber–Optic Sensing in the Oil and Gas Industry
TL;DR: In this paper , the deployment of fiber-optic Rayleigh-based distributed acoustic sensing (DAS), Raman-based DTS, and Brillouin-based Distributed Temperature and Strain Sensing (DTSS) in the oil and gas industry is reviewed.
Proceedings ArticleDOI
Investigating the performance of apodized Fiber Bragg gratings for sensing applications
TL;DR: In this article, a comprehensive investigation for using apodized fiber bragg gratings in sensing applications is presented, where different evaluation parameters such as, reflectivity, sidelobes, and fullwidth-half-maximum (FWHM) are tested in order to determine the most proper apodization profile for sensors.
